Sentences with phrase «glacier area»
The phrase "glacier area" refers to a location or region that has a lot of glaciers. A glacier is a large mass of ice that moves very slowly, like a river of ice. So, a glacier area is a place where there are many of these icy rivers, usually found in cold and mountainous regions. Full definition
